To all whom it muy concern:

Be it known that I, JOHN T. AUSTIN, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Or an-Actions, of which the following is a fu clear, and exact specification.

This invention relates to pipe-organs and similarly-operated instruments, and consists in .an Improved construction and arran ement of the key-operated devices and t e coupler parts associated therewith.

'Figure 1 is a plan yiew of an or an-key, showing it connected with devices emodying this invention. Fig. 2 is a sectional sideview of'Fig. 1, taken on the line 2 2. Fig. 3 is a side view showing a modified form of the key and valve. Fig. 4 is a front view of the valve in section through the center of the slide 22.

In the embodiment of this invention herein shown the' key-valves which control the individual notes and the sliders which control the different ranges of stops or pipes are on the open or atmosphere side ofthe actions, instead of bein located in a wind-chest or vacuum-chest. T 's arra ement enables these important parts to remam always open for ready inspection and repairs without having to open the air-ti ht joints of inclosed chests and it also enab es connection to be made between the manual-keys and the keyvallilfes without passing throughwind-chest wa s.

Each manual-key 11 is supported on the base 12 by a pivot-pin 14 or in any convenient way. Extending along the inner ends of the ke s is the` duct-bar 13, in which are formed t e ports for each ke and the connecting passa es for the coup ers. vThe key 11 is assume to Ybe one of the keys of the swell-organ, controlling the ports 26 27, and 28 although the invention 1s equally applica le to any of the manual or pedal keys of the organ or .to any desired number of ports. Each port 26 leads to amixing or combining passage 35, connected in this case by means of the tube 40 with the operating devices of the regular or "unisonf series of pipes controlled by the key 11. The port 27 1s connected, through the pipe 32, wlth the combining-passage 4l of the su eroctave, i

and the port 28 is connected by t e tube 31 with the combining-passage 42 of the suboctave. Pipes 36 and 37 lead from the passage 35 to the ports 46 and 47, res ectively, of the sub and super octave keys. l`hepipes 38 and 39 lead, respectively, to Orts controlled by the corresponding keys o other keyboardsas, for example, the keys of the great and pedal organs. The arrangement o thekeys and pipes is best shown in Fig. 1, where, for the sake of clearness, only one set of key connections is completely shown It will be understood, however, that each key of the series has a set of Orts and connections similar to that shown or the key 11. By this arran ement the duct-bar 13 is universal to all t e keys of one manual, and the coupler connections of each key are made direct from one ort in the duct-bar to another without the lntervention of the additional duct-bar or mixerf heretofore used for joining the coupler connections, thisA construction and arrangement being cheaper, more compact, and less liable to leakage.

All the ports in the range or longitudinal series of ports. represented y the port 28 are simultaneously opened or closed by means of a slider 22 of a well-known type, furnished with apertures 43, so disposed as to be thrown into and out of .re ister with the ran e of Orts 28 when the slider 22 is moved en wise. xIhe slider may be moved by hand or by any of the Well-known devices for this purpose. Similar sliders 23 and 24 operate to open and close the two ranges of Orts represented by the ports 27 and 26. 'l e sliders are ided in their respective paths by pins 25 in t e top ofthe duct-bar 13 or in any other Well-known way. In Fig. 1 the slider 22 is shown in its "OH position, with the apertures 43 out of register with the ports 28, While the two sliders 23 and 24 are shown in their on position, with the apertures 44 and 45 coinciding with the ports 27 and 26. f Sliders of this kind are commonl inclosed on all sides in a casing, the topan bottom walls of which are apertured in coincidence with the slider-apertures when the slider is in its on position, and

against the outer ,sides of the casing, or at any rate do not bear directly against the sliders themselves. These casin s and the sliders, being commonly made o wood, are F liable to shrink and warp, thereby forming X00 the key-valves controlling the apertures'close openings through or along which the air can leak either through the casing, thereby wasting the pressure, or along the slideway from one aperture to another, thus rendering the notes liable to be sounded incorrectly. In the present invention the sliders are not inclosed in a casing, but lie against an outer surface of the duct-bar 13, where they can readily be inspected, removed, and replaced. The key-valves when in their closed positions rest directly against the outer sides of the slideways. The latter, being quite flexible, conform to the surface of the duct-bar under the pressure of the key-valves, which in closing the apertures serve at the same time to press the sliders to their seats on the duct ar, thereby stopping all leakage that might. otherwise occur. Moreover, the seats for the sliders, being in the atmosphere and not incased, may be readily examined and repaired whenever needed.

Each ke 11 o erates a valve 17, which in the form s own 1n Figs. 1 and 2 is hinged at 18 on the bar 13. The valve is pressed down, ward by the spring 19 u on the sliders 22, 23, and 24 and covers the tlliree apertures 43, 44, and 45, correspondin to the key 11, Whether the sliders are in eit er their off or on position. The valve 17 is preferably provided on its under side with a cushion 20, of felt or other suitable material, faced with leather 2i Fig. 4.

It Will be seen that with the above-described arrangement it takes the cooperation of both the slider and the key to uncover any one of the ports, thus forming a dual control for each port. If the key be operated While the slider is in the oil' position, the port will be covered by the slider, and if the slider be moved to the on position and the key not oplerated the port will be closed by the valve w ich 'still covers the aperture in the slider, The series of valves, each pressed inde endently by its spring upon the sliders, hol the latter in close contact with its seat around the ports despite any inequalities or variations due to the swelling and shrinking of the wood, of which the associated members are usuali com osed.

vIn ig. 3 t e key 51 is made long enough to serve the u ose of a valve as wel] as a key by providlng it with an extension 52, to which is Vattached the cushion 53. The spring 54 holds the end of the key down upon the slides 56 and the ports 58, thus also providing a dual-control arran ement for the ports which operates similar y to that shown in the other iigures. l

In Fi 4 is shown in enlarged scale the location o the port 28 at one side of the center line of the valve 17. This ermits a maximum of movement for the side and a maximum size for the port for a given width of valve and precludes all danger of the leakage which would result when shifting the slider organ designer.

if one edge of the aperture were to pass from beneath the valve, and thus become uncovered while the other edge still overlapped the ort. p It is obvious that the duct-bar arrangement herein shown and described may be made to provide for other properly-related combinations of notes-such as thirds, fifths, @scf-as Well as for the super and sub octaves. Also the combining-passages of the notes need not be connected with the pipes of their respective unison series, but may be connected to other passages or actuatn devices according to the skill and fancy o the The term range as used in connection with a series of ports may consist of a longitudinal line of ports for only a portion of one keyboard, as well as for the whole of it.
